Brian Arden Winery in the Napa Valley, California town of Calistoga constructed a new facility for the production of their fine distinctive varietal wines in the winter of 2014. The civil engineers for the project selected a large scale RainSpace Stormwater Management and Water Storage system consisting of multiple underground inter-connected chambers. The beautiful site esthetics were preserved by placing the System under the parking lot. This RainSpace System provides both water storage for on-site irrigation and infiltration treatment of stormwater collected from building roofs and hardscape. The collected water flows into a RainSpace Clarifier Filter and Pump Well with a Sediment Isolation Filter Tube (SIFT) to remove debris and settle and isolate sediment from the system.
